The Catch series roams New York — and across the country — bringing a show with something for all tastes. Bizarre experimental dance; left-field, poignant rumination on the Constitution; last weekend, the 27th edition even featured a death metal-inspired "poperetta" about two lady centaurs on a journey through outer space to find lusty crystals, and included a hysterical rendition of a Boyz II Men track. Next weekend, the feature is a short play satirizing the American peace movement, but it's anyone's guess exactly what that entails.
